Hi, I have been trying to solve some mechanics problems and I can come up with the right equation, but I don't know how to solve it... For example: 490.5cos(theta) - 3600cos(theta)sin(theta) + 1800sin(theta) = 0 i need to solve for theta here its one equation and one unknown...

Here is the answer: (a) d/dx(0.5v2) = ( x + 3 ) => v2/2 = x2/2 + 3x + C => v2 = x2 + 6x + C when t=0, x=0 and v=3 Therefore, c = 9 v2 = x2 + 6x + 9 => v2 = (x+3)2 => v = (x+3) (b) v = x+3 a = x+3 a =...
